We are hiring a postdoctoral researcher for up to 4 years. The candidate must have PhD degree in information and/or communications theory or signal processing. A strong background on Shannon theory is highly desirable. Affinity with optical communications, the Nonlinear Schrödinger Equation (NLSE), or with optical physical layer (including channel modeling), is beneficial, but not mandatory. Candidates with a degree in mathematics or nonlinear physics are also welcome to apply.
